What probiotic has to do with bad breath?

Clinical studies have demonstrated reduction of bad breath can be done by reducing the bad bacteria in the oral cavity3. Therefore, supplementing probiotic can help in reducing bad breath by kill off the bad bacteria in the oral cavity.

Not all the probiotics the same, probiotic is strain-specific, meaning each strains deliver different health benefits to the body. In order to fight for bad breath, one need to consume the right strains of probiotic which have been clinically proven for its health benefits. Streptococcus salivarius K12 is a specific strain of Streptococcus salivarius which able to produce powerful anti-microbial substances known as BLIS – Salivaricin A and B4. Studies have shown Streptococcus salivarius K12 is able to reduce bad breath within 7 days4.

 

Streptococcus salivarius K12 work through triple “PUNCH” of action4,5:

  1. Bacterial replacement therapy: Competing with pathogenic organism for colonization sites
  2. Producing anti-microbial substances known as BLIS – Salivaricin A and B
  3. Interacting with host cell to modulate the immune system
